27-year-old Lin Rong re-entered Japan even though she had earlier been deported back to China. She wasn't caught until she was arrested on other charges, because her fingerprints were different. Lin had undergone surgery to have her left fingerprints moved to her right hand, and vice versa!

Local media reports said Ms Lin had undergone surgery to swap the fingerprints from her right and left hands.

Skin patches on her thumbs and index fingers were removed and then re-grafted on to the matching digits of the opposite hand.

Japanese newspapers said police had noticed that Ms Lin's fingers had unnatural scars when she was arrested last month for allegedly faking a marriage to a Japanese man.
